Inert gas generator

As the size of oil tankers increased towards the end of the 1960s, incidents of explosions in cargo tanks also increased. These often disastrous incidents led to the introduction of regulations, systems and operational procedures designed to improve the safety of all types of tankers.

This e-learning module first covers the background for the need for inert gas systems on board tankers before looking in detail at the design, operational and maintenance aspects of independent, oil fired inert gas generators. It will give the user the necessary background knowledge and awareness to allow them, with the aid of specific manufacturer’s operational and maintenance manuals, to safely operate and maintain most types of inert gas generator equipment. Although primarily intended for Engineer Officers at the operational level it will also be a useful tool for refresher training for more experienced engineering personnel and will also provide useful knowledge to any on board personnel involved with cargo operations on board tankers fitted with this type of equipment.
